Rotary Jog low

how i can downgrade to linuxcnc 2.9?

the installer makes 2.10 automaticly....



by the way how i can do on REF Y to ref my second y Axis too?
on REF Y only axis.y move... but i have a axis.y2 too.

assuming you are building source, before make, type
cd ~/linuxcnc-dev/src
git checkout 2.9

I see the installer use brench 2.9

But at the the end that was installing the 2.10 pre0 deb.

So it works now. I will test it few times.
